Answer:
-x + 10
Step-by-step explanation:
(x + 7) - (2x-3)
x + 7 - 2x - 3
x - 2x
-x + 7 + 3
-x + 10
One pound bag cost $1.10
2 pound bag cost $1.98 which is .99 per pound
3 pound bag cost $2.85 which is .95 per pound
The more amount you buy the cheaper it is per pound.
Answer: the velocity and position vector is given by;
v(t) = 3i + 2j + (1-32t)k
r(t) = (3t)i + (5-2t)j + (2+t-16t^2)k
The position at time t=2; r(2)
r(2) = 6i + j - 60k
Step-by-step explanation:
Shown in the attachment.
Answer: y = -1x + 8
Step-by-step explanation: linear equations must be written in the format
y = mx + b from.
m represents the slope which it -1
b represents the y-intercept which is 8.
Just substitute the slope and y-intercept in the m and b places and that is a linear equation.
The expression for finding the amount of money earned on interest is

where
P = principal (money you started with)
r = rate (in decimal form)
n = number of times compounded per year
t = time (in years)
In this case:
P = 3000
r = 0.02 (because 2% in decimal form is 0.02)
n = 1 (because it is compounded once every year)
t = 16 (because she got the money when she was 2 and we are calculating it for when she turns 18, 16 years later)
So, you plug it in:

So, the answer is (1) <span>3000(1 + 0.02)^16</span>
